S)-3,7-Dimethyl-2-oxo-6-octene-l,3-diol (39) was recently identified as the aggregation pheromone of the Colorado potato beetle (Leptinotarsa decem-lineata), and synthesized by Oliver et al., starting from (S)-linalool [86]. An improved synthesis of (S)-39 by Mori is shown in Scheme 57 [87]. Enzymatic acetylation of ( )-2,3-epoxynerol (A) with vinyl acetate and lipase PS gave B together with C. The acetate B was converted to a multi-gram quantity of (S)-39 according to Oliver [86].

The male produced aggregation pheromone of the Colorado potato beetle, Lepitnotarsa decemlineata, (5)-l,3-dihydroxy-3,7-dimethyl-6-octen-2-one and its (f )-isomer were synthesized using lipase-catalyzed asymmetric acetylation of +)-2,...

In potato pectic polysaccharides, the RG-I domain accounts for 75% of the total, a much higher proportion than in pectic polysaccharides of other species ( 20-35%) (Oomen et al., 2003 Mohnen et al., 2008). RG-1 consists of a backbone of alternating a-D-galacturonic acid and a-L-rhamnosyl residues, linked as indicated in Figure 3.3, which in potato accounts for 14% of the total RG-1 (Oomen et al., 2003). Although the galacturonic acid residues are probably not methyl-esterified, they may be acetylated. This is so in potato, where a preparation...
